What the Specifications Mean in Practice

Our notes on reading these numbers — LiveInSmart guidance, not manufacturer claims.

• A specification does not guarantee a listening result — room size, furnishings, placement and calibration change what you hear.

Who Should Consider It

Typical uses for the SRT 4201:

• The LFE (.1) channel in a home theatre
• Adding deep bass to stereo music

When Another Option May Suit Better

You may prefer a different configuration if the room is very small and neighbours share walls — a smaller driver or careful level setting may suit better.

What Else You Need for a Working System

Connect to the subwoofer (LFE) output of an AV receiver. Final matching should be checked by an audio consultant against your room and equipment.
